Gas fire extinguishing controller designed for automatic gas fire extinguishing system, financial automatic detection, automatic alarm, automatic fire extinguishing as one of the controllers, gas fire extinguishing controller can be connected to smoke, temperature and fire detectors, emergency start and stop metal push buttons, automatic hand Switch, gas spray signal lights, sound and light alarms and other equipment, and provide the interface to drive the solenoid valve, used to start the gas fire extinguishing equipment.
1, manual control: the gas fire extinguisher control mode selection button, dial "manual" position, the fire extinguishing system is in manual control state. When a fire broke out in the protected area, press the emergency start or stop metal push button or start the metal push button on the controller to start the fire extinguishing system according to the prescribed procedure to release the fire extinguishing agent to extinguish the fire. In the automatic control state, can still achieve the electrical manual control.
2, automatic control: the gas fire extinguisher control mode selection button, dial "automatic" position, the fire extinguishing system is in automatic control state, when the protection zone fire, the fire detector sends a fire signal, the alarm fire extinguishing controller Send out the sound and light alarm signals, meanwhile send linkage command to close the interlocking equipment. After a delay time, issue a fire extinguishing instruction, open the solenoid valve to release the starting gas, and start the gas to open the corresponding selection valve and container valve Valve), release the fire extinguishing agent, the implementation of fire.
3, Mechanical emergency manual operation: When the protection zone fire, the controller can not issue a fire instruction, the relevant personnel should be informed to leave the scene, shut down the linkage equipment, and then pull out the corresponding start bottle group to start the manual valve on the insurance card, pressure Under the handle to open the start valve, release the start gas, you can open the selector valve, container valve (bottle valve), the release of fire extinguishing agent, the implementation of fire fighting. In this case, when starting the valve repair or start-up gas cylinder gas pressure is not enough to work, then should open the corresponding selection of fire extinguishing area valve handle, open the pressure arm, open the selector valve, and then open the container valve in the area (bottle Head valve) on the manual handle to open the container valve (bottle valve), release the fire extinguishing agent, the implementation of fire fighting.
During the delay time and found abnormal circumstances, do not need to start the fire extinguishing system for fire extinguishing, you can press the manual control box or gas fire extinguisher emergency stop metal push button to stop the controller fire instruction issued.
Gas fire extinguishing controller can also be connected with the fire alarm controller, the implementation of remote control. Gas fire extinguishing can be used to protect against the following substances: 1, electrical and electronic equipment fire; 2, combustible liquids and meltable solid fire; 3, solid surface fire; 4, before the fire can cut off gas source gas
